I do EXACTLY the same thing as Spensar: I collect a bunch of gallon jugs and put just how much LC I want to go in every day and fill the rest with clean tap water. I tell my "deputy" to pour in one jug every day. Nice and simple. If I'm short on jugs, I put more LC in each jug and have the "deputy" pour in a jug every other day. It's simple and it works.
